No, my last name is my married name.  I kept it not because I wanted to stay with his name but because everyone knew me by that name, my kids have that last name etc.  Eventually I'll go back to my maiden name or if I remarry at any point I'll take his name.  I actually want to get rid of his name and it kind of bugs me that it's his but for now for the ease of the kids and everything else, I'm waiting.
